Azoles having an insecticidal action

ABSTRACT

The present application relates to novel heterocyclic compounds, to processes for their preparation, and to their use as crop protection agents, particularly for controlling animal pests.

The present invention relates to novel heterocyclic compounds, to processes for their preparation and to their use as crop protection agents, in particular for controlling animal pests.

Various amino-substituted iminoheterocycles, such as, for example, 2-imino-4-amino-thiazoline, are already known as intermediates for dyes and active compounds or else as substances having a radio-protective effect. However, a use as crop protection agents and in particular for controlling animal pests has hitherto not been disclosed (cf. DE-A 2 921 683; S. M. Abdelall et al. J. heterocyclic Chem. 25, 1849-1956, 1988; E. N. Goncharenko et al. Radiobiologiya 22(2), 252-255, 1982).

Other amino-substituted iminoheterocycles, such as, for example, 3-amino- and 3-alkylamino-5-imino-2,5-dihydrofurans are known (cf. S. R. Landor J. Chem. Eoc. Perkin Trans. 1201-1204, 1991; M. Yu. Skvortsov et al. Zh. Org. Khim. 27(3), 526-530, 1991; M. Yu. Skvortsov et al. Zh. Org. Khim. 22(2), 255-259, 1986; M. Yu. Skvortsov et al., Zh. Org. Khim. 21(1), 221-222, 1985). Certain iminoheterocycles of this structural type, for example 2-imino-4-(2-hydroxyethylamino)-5,5-dimethyl-2,5-dihydrofuran, have anti-inflammatory and analgesic activity (cf. B. A. Trofimov et al. SU 1392872, 1998). However, nothing has been disclosed concerning the use as crop protection agents, in particular for controlling animal pests.

This invention now provides novel heterocyclic compounds of the formula (I)

in which

-   A represents in each case optionally substituted aryl or hetaryl or     heterocyclyl, -   R¹ represents hydrogen or C₁-C₃-alkyl, -   R² represents hydrogen or C₁-C₃-alkyl, -   R³ represents hydrogen or C₁-C₃-alkyl, -   R⁴ represents hydrogen or C₁-C₃-alkyl, -   X represents N or CH, -   Y represents CN or NO₂, -   Z represents CH₂, O, S, SO, SO₂ or NR⁵ and -   R⁵ represents hydrogen or C₁-C₃-alkyl.

Furthermore, it has been found that the compounds of the formula (I) are obtained when compounds of the formula (II)

are reacted with suitable cyanating agents (to obtain compounds of the formula (I) in which Y represents CN) or with suitable nitrating agents (to obtain compounds of the formula (I) in which Y represents NO₂).

Finally, it has been found that the novel compounds of the formula (I) have strongly pronounced biological properties and are suitable especially for controlling animal pests, in particular insects, arachnids and nematodes, encountered in agriculture, in forests, in the protection of stored products and materials and in the hygiene sector.

The formula (I) provides a general definition of the compounds according to the invention.

Alternative possibilities are also reaction sequences such as, for example, O-alkylation with R₃O⁺BF₄ ⁻ (R: methyl, ethyl) (H. Meerwein et al., Justus Liebigs Ann. Chem. 641, (1961) p. 1) and subsequent reaction of the intermediates with anhydrous NaSH (R. E. Eibeck, Anorg.

In general, it is advantageous to carry out this process in the presence of diluents. Diluents are advantageously employed in such an amount that during the entire process the reaction mixture remains readily stirrable. Suitable diluents for carrying out the process according to the invention are all inert organic solvents.

Examples which may be mentioned are: halogenated hydrocarbons, in particular chlorinated hydrocarbons, such as tetrachloroethylene, tetrachloroethane, dichloropropane, methylene chloride, dichlorobutane, chloroform, carbon tetrachloride, trichloroethane, trichloroethylene, pentachloroethane, difluorobenzene, 1,2-dichloroethane, chlorobenzene, bromobenzene, dichlorobenzene, chlorotoluene, trichlorobenzene; alcohols, such as methanol, ethanol, isopropanol, butanol; ethers, such as ethyl propyl ether, methyl tert-butyl ether, anisole, phenetol, cyclohexyl methyl ether, dimethyl ether, diethyl ether, dipropyl ether, diisopropyl ether, di-n-butyl ether, diisobutyl ether, diisoamyl ether, ethyleneglycol dimethyl ether, tetrahydrofuran, dioxane, dichlorodiethyl ether and ethylene oxide and/or propylene oxide polyethers; amines, such as trimethylamine, triethylamine, tripropylamine, tributylamine, N-methyl-morpholine, pyridine and tetramethylenediamine; nitrated hydrocarbons such as nitromethane, nitroethane, nitropropane, nitrobenzene, chloronitrobenzene, o-nitrotoluene; nitriles, such as acetonitrile, propionitrile, butyronitrile, isobutyronitrile, benzonitrile, m-chlorobenzonitrile and also compounds such as tetrahydrothiophene dioxide and dimethyl sulphoxide, tetramethylene sulphoxide, dipropyl sulphoxide, benzyl methyl sulphoxide, diisobutyl sulphoxide, dibutyl sulphoxide, diisoamyl sulphoxide; sulphones, such as dimethyl sulphone, diethyl sulphone, dipropyl sulphone, dibutyl sulphone, diphenyl sulphone, dihexyl sulphone, methyl ethyl sulphone, ethyl propyl sulphone, ethyl isobutyl sulphone and pentamethylene sulphone; aliphatic, cycloaliphatic or aromatic hydrocarbons, such as pentane, hexane, heptane, octane, nonane and industrial hydrocarbons, for example White Spirits having components of boiling points in the range of, for example, from 40° C. to 250° C., cymene, petroleum fractions within a boiling point range of from 70° C. to 190° C., cyclohexane, methylcyclohexane, petroleum ether, ligroin, octane, benzene, toluene, chlorobenzene, bromobenzene, nitrobenzene, xylene; esters, such as methyl acetate, ethyl acetate, butyl acetate, isobutyl acetate, and also dimethyl carbonate, dibutyl carbonate, ethylene carbonate; amides, such as hexamethylphosphoric triamide, formamide, N-methylformamide, N,N-dimethylformamide, N,N-dipropylformamide, N,N-dibutylformamide, N-methylpyrrolidine, N-methylcaprolactam, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidine, octylpyrrolidone, octylcaprolactam, 1,3-dimethyl-2-imidazolinedione, N-formylpiperidine, N,N′-1,4-diformylpiperazine; ketones, such as acetone, acetophenone, methyl ethyl ketone, methyl butyl ketone.

Process according to the invention can, of course, also be carried out in mixtures of the solvents and the diluents mentioned.

The diluents to be used depend on the sulfurising agent used in each particular case.

However, preferred diluents for the thionation are aromatic hydrocarbons, such as benzene, toluene, chlorobenzene, bromobenzene, nitrobenzene, or xylene, ethers, such as ethyl propyl ether, methyl tert-butyl ether, anisole, phenetol, cyclohexyl methyl ether, tetrahydrofuran or dioxane.

By reaction with HgCl₂/(C₂H₅)₃N/H₂NCN the compounds of the formula (IV) can be converted directly into compounds of the formula (I) in which Y represents CN (cf. Can. J. Chem. 1985, 63, 3089 and also J. Med. Chem. 1988, 31, 264).

The compounds of the formula (IV) can furthermore be converted by aminolysis with ammonia in the presence of mercury salts, by heating in a reaction vessel with aqueous ammonia in the presence of suitable oxidizing agents, such as, for example, tert-butyl hydroperoxide (TBHP), into compounds of the formula (II) (cf. M. G. Bock et al., J. Med. Chem. 1988, 31, 264-268; N. W. Jacobsen et al., Aust. J. Chem. 1987, 40, 491-499; T. Lindel et al., Tetrahedron Lett. 1997. 38 (52), 8935-8938).

Reaction of the compounds of the formula (IV) (Z=NH) with alkyl iodides in the presence of bases gives compounds of the formula (III) (Z=N) (see T. Lindel et al., Tetrahedron Lett. 1997. 38, (52), 8935-8938; M. G. Bock et al., J. Med. Chem. 1988, 31, 264-268). In the compounds of the formula (III), R represents, for example, alkyl, preferably methyl. Compounds of the formula (III) in turn can be converted in a manner which is known in principle by reaction with a mixture of ammonia/ammonium chloride into compounds of the formula (II) (cf. T. Lindel et al., Tetrahedron Lett. 1997. 38, (52), 8935-8938).

The compounds of the formula (II) can be converted with cyanating agents or nitrating agents into compounds of the formula (I).

A suitable cyanating agent is, for example, cyanogen bromide (BrCN). The reaction is carried out in a generally known manner (cf. also U.S. Pat. No. 4,098,791 and DE 29 16 140).

Nitrations can be carried out by customary processes as described, for example, in Houben-Weyl, Methoden der Organischen Chemie, [Methods of Organic Chemistry], Volume XI/2 (Georg Thieme Verlag—Stuttgart 1958), pp. 99-116. Nitrating agents which may be mentioned are fumed or 100% strength nitric acid (preparation of anhydrous nitric acid cf. F. D. Chattaway, Soc. 97, 2100 (1910), if appropriate in the presence of sulfuric acid (W. J. Middleton et al., J. Heterocycl. Chem. 7, 1045-1049 (1970); L. W. Deady et al., Aust. J. Chem. 35 (10), 2025-2034 (1982); EP 0192060) or the use of nitric acid esters, acetyl nitrate or nitronium tetrafluoroborate. The reaction is preferably carried out in a generally known manner using acyl nitrate.

The compounds of the formula (I) according to the invention are active, in particular, against sucking insects.

At certain concentrations or application rates, the compounds according to the invention may, if appropriate, also be used as herbicides and microbicides, for example as fungicides, antimycotics and bactericides. If appropriate, they may also be used as intermediates or precursors for the synthesis of further active compounds.

All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (inclusive of naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and recombinant methods or by combinations of these methods, inclusive of the transgenic plants and inclusive of the plant cultivars protectable or not protectable by plant breeders' rights. Plant parts are to be understood to mean all above-ground and underground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruit bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include harvested material, and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, offsets and seeds.

Treatment according to the invention of the plants and plant parts with the active compounds is carried out directly or by allowing the compounds to act on their surroundings, environment or storage space by the customary treatment methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspension-emulsion concentrates, natural and synthetic materials impregnated with active compound, and microencapsulations in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam-formers.

If the extender used is water, it is also possible to employ for example organic solvents as auxiliary solvents. Essentially, suitable liquid solvents are: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, and also water.

Solid Carriers are:

-   for example ammonium salts and ground natural minerals such as     kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or     diatomaceous earth, and ground synthetic minerals, such as highly     disperse silica, alumina and silicates; suitable solid carriers for     granules are: for example crushed and fractionated natural rocks     such as calcite, marble, pumice, sepiolite and dolomite, and also     synthetic granules of inorganic and organic meals, and granules of     organic material such as sawdust, coconut shells, maize cobs and     tobacco stalks; suitable emulsifiers and/or foam-formers are: for     example nonionic and anionic emulsifiers, such as polyoxyethylene     fatty acid esters, polyoxyethylene fatty alcohol ethers, for example     alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates,     arylsulphonates and also protein hydrolysates; suitable dispersants     are: for example ligno-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyes, such as alizarin dyes, azo dyes and metal phthalocyanine dyes, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

The active compound according to the invention can be present in its commercially available formulations and in the use forms, prepared from these formulations, as a mixture with other active compounds, such as insecticides, attractants, sterilizing agents, bactericides, acaricides, nematicides, fungicides, growth-regulating substances or herbicides. The insecticides include, for example, phosphoric acid esters, carbamates, carboxylates, chlorinated hydrocarbons, phenylureas and substances produced by microorganisms, inter alia.

The active compounds of the formula (I) according to the invention are also suitable for controlling arthropods which infest agricultural productive livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese and bees, other pets, such as, for example, dogs, cats, caged birds and aquarium fish, and also so-called test animals, such as, for example, hamsters, guinea pigs, rats and mice. By controlling these arthropods, cases of death and reduction in productivity (for meat, milk, wool, hides, eggs, honey etc.) should be diminished, so that more economic and easier animal husbandry is possible by use of the active compounds according to the invention.

The active compounds according to the invention are used in the veterinary sector in a known manner by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, such as, for example, by injection (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of moulded articles containing the active compound, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

When used for cattle, poultry, pets and the like, the active compounds of the formula (I) can be used as formulations (for example powders, emulsions, free-flowing compositions), which comprise the active compounds in an amount of 1 to 80% by weight, directly or after 100 to 10 000-fold dilution, or they can be used as a chemical bath.

It has furthermore been found that the compounds according to the invention also have a strong insecticidal action against insects which destroy industrial materials.

The following insects may be mentioned as examples and as being preferred—but without any limitation:

Beetles, such as

Bristletails, such as Lepisma saccharina.

Industrial materials in the present context are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cards, leather, wood and processed wood products and coating compositions.

Wood and processed wood products are materials to be protected, especially preferably, from insect infestation.

Wood and processed wood products which can be protected by the agent according to the invention or mixtures comprising this are to be understood as meaning, for example:

-   building timber, wooden beams, railway sleepers, bridge components,     boat jetties, wooden vehicles, boxes, pallets, containers, telegraph     poles, wood panelling, wooden windows and doors, plywood, chipboard,     joinery or wooden products which are used quite generally in     house-building or in building joinery.

The active compounds can be used as such, in the form of concentrates or in generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyes and pigments, and also other processing auxiliaries.

The insecticidal compositions or concentrates used for the preservation of wood and wood-derived timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the nature and occurrence of the insects and on the medium. The optimum amount employed can be determined for the use in each case by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.

Solvents and/or diluents which are used are an organic chemical solvent or solvent mixture and/or an oily or oil-like organic chemical solvent or solvent mixture of low volatility and/or a polar organic chemical solvent or solvent mixture and/or water, and if appropriate an emulsifier and/or wetting agent.

Organic chemical solvents which are preferably used are oily or oil-like solvents having an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C. Substances which are used as such oily or oil-like water-insoluble solvents of low volatility are appropriate mineral oils or aromatic fractions thereof, or solvent mixtures containing mineral oils, preferably white spirit, petroleum and/or alkylbenzene.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum and aromatics having a boiling range from 160 to 280° C., turpentine oil and the like, are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-like solvents of low volatility which have an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., can be replaced in part by organic chemical solvents of high or medium volatility, provided that the solvent mixture likewise has an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

According to a preferred embodiment, some of the organic chemical solvent or solvent mixture is replaced by an aliphatic polar organic chemical solvent or solvent mixture. Aliphatic organic chemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organic chemical binders which are used in the context of the present invention are the synthetic resins and/or binding drying oils which are known per se, are water-dilutable and/or are soluble or dispersible or emulsifiable in the organic chemical solvents employed, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-coumarone resin, silicone resin, drying vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. Dyestuffs, pigments, water-repelling agents, odour correctants and inhibitors or anticorrosive agents and the like which are known per se can additionally be employed.

It is preferred according to the invention for the composition or concentrate to comprise, as the organic chemical binder, at least one alkyd resin or modified alkyd resin and/or one drying vegetable oil. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether or ketones, such as benzophenone or ethylenebenzophenone.

Possible solvents or diluents are, in particular, also water, if appropriate as a mixture with one or more of the abovementioned organic chemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective preservation of wood is achieved by impregnation processes on a large industrial scale, for example vacuum, double vacuum or pressure processes.

The ready-to-use compositions can also comprise other insecticides, if appropriate, and also one or more fungicides, if appropriate.

Possible additional mixing partners are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an explicit constituent of the present application.

Especially preferred mixing partners which may be mentioned are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron, transfluthrin, thiacloprid, methoxyphenoxide and triflumuron, and also fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorfluanid, tolylfluanid, 3-iodo-2-propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

The compounds according to the invention can at the same time be employed for protecting objects which come into contact with salt water or brackish water, such as hulls, screens, nets, buildings, moorings and signalling systems, against fouling.

Fouling by sessile Oligochaeta, such as Serpulidae, and by shells and species from the Ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.

Apart from fouling by algae, for example Ectocarpus sp. and Ceramium sp., fouling by sessile Entomostraka groups, which come under the generic term Cirripedia (cirriped crustaceans), is of particular importance.

Surprisingly, it has now been found that the compounds according to the invention, alone or in combination with other active compounds, have an outstanding antifouling action.

Example IX-1 6-chloro-3-(N-(2,2-dimethyl-2H-azirin-3-yl)-N-methyl)-aminomethylpyridine

In a secured 250 ml four-necked flask fitted with dropping funnel, internal thermometer and dry-ice condenser on an ice-bath, 1.78 g (9.0 mmol) of diphosgene are initially charged in 20 ml of abs. CH₂Cl₂. At 0-5° C. and under nitrogen, a solution of 3.63 g (15.0 mmol) of N-(6-chloro-3-pyridylmethyl)-N-methyl-2-methylpropanethioamide in 10 ml of abs. CH₂Cl₂ are added dropwise. Four drops of abs. DMF are then added and the reaction mixture is slowly warmed to room temperature and stirred for four hours. Excess phosgene and solvent are then removed completely under water-pump vacuum via a cold trap. The solid that remains is, under nitrogen, dissolved in 60 ml of abs. THF and cooled to 0-5° C., and 1.68 g (15.0 mmol) of DABCO are added with vigorous stirring. The reaction mixture is warmed to room temperature and stirred for 45 minutes. The resulting voluminous precipitate is filtered under inert gas via an elbow fitting and washed twice with ab. THF. Under nitrogen, without further work-up, 1.95 g (30 mmol) of solid sodium azide are added to the resulting clear solution and the mixture is stirred for 48 hours. To isolate the product, the inorganic salts are filtered off, the solvent is removed under reduced pressure and the resulting residue is purified by silica gel column chromatography using the mobile phase ethyl acetate/methanol=10/2 (R_(f)=0.2).

Potassium N-cyanoiminomethylsulphanylmethanethiolate (XI) a) Preparation of the Dipotassium Salt of Cyanoimidodithiocarbonic Acid

Under an atmosphere of nitrogen, in a 500 ml four-necked flask fitted with overhead stirrer, dropping funnel, thermometer and reflux condenser, 21.0 g (0.50 mol) of cyanamide in 40 ml of ethanol are cooled to 0° C. At this temperature, 41.9 g (0.55 mol) of carbon disulfide and then 56.1 g (1.00 mol) of potassium hydroxide in 180 ml of ethanol are successively added dropwise such that the internal temperature does not exceed 5° C. (about 4 hours). After the addition has ended, the cooling bath is removed and the mixture is stirred at room temperature overnight. The resulting solid is filtered off, washed with ethanol and dried under reduced pressure. The resulting salt is hygroscopic and, during filtration, should only be in contact with the atmosphere/atmospheric humidity for a short time. For the next step, the salt is used as crude product. The yield is 75-80% of theory.

b) Potassium N-cyaniminomethylsulfanylmethanethiolate

77.7 g (0.40 mol) of the crude product are dissolved in a mixture of 270 ml of acetone and 300 ml of water and cooled to 0° C. At this temperature, with vigorous stirring, 56.8 g (0.40 mol) of methyliodide in 150 ml of acetone are slowly added dropwise over a period of three hours. After the addition has ended, the reaction mixture is stirred at 0° C. for one hour and then at room temperature for another three hours. On a rotary evaporator, all solvents are removed to dryness. The residue is taken up in 250 ml of abs. acetone and, using a rotary evaporator, concentrated to half of its original volume. For crystallisation of the resulting potassium iodide, the reaction mixture is kept in a fridge overnight. The resulting solid is filtered off and the filtrate is concentrated further, almost to dryness. In the cold, the desired product precipitates out. The last step can now be repeated to complete remove the potassium iodide. The yield is 75-80% of theory. The analytical data are consistent with the literature.

Test animals: Adults of Ctenocephalides felis Solvent: Dimethyl sulphoxide (DMSO)

To produce a suitable preparation, a suitable solution of active compound is prepared from 20 mg of active compound and 1 ml of DMSO. 20 μl of this formulation are added to 4 ml of citrated cattle blood and stirred.

20 unfed adult fleas (Ctenocephalides felis, strain “Georgi”) are placed into a chamber (Ø 5 cm) whose top and bottom are closed with gauze. A metal cylinder whose underside is covered with parafilm is placed onto the chamber. The cylinder contains the 4 ml of blood/active compound formulation which can be taken up by the fleas through the parafilm membrane. Whereas the blood is warmed to 37° C., the temperature in the area of the flea chambers is adjusted to 25° C. Controls are mixed with the same volume of DMSO, without addition of a compound. The determinations are carried out triplicate.

After 24 h, the mortality in % is determined.

Compounds which effect an at least 25% kill of the fleas within 24 h are judged to be effective.
